(Phys.org)—Raising the temperature is one easy way to get chemical reactions to speed up. This temperature dependence can be accurately described by a simple exponential relation known as the Arrhenius ...

It was a bit like making a CT scan of a patient's head and finding he had very little brain or making a PET scan of a dead fish and seeing hot spots of oxygen consumption. Scientists making seismic images ...

A new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) points to the deep ocean as a major source of dissolved iron in the central Pacific Ocean. This finding highlights the vital ...

It's no exaggeration to say the tropics drive our planet's carbon cycle – the constant transfer of carbon back and forth, on a global scale, between living things and the environment. Understanding the ...

When you open the back of a fine watch, you see layer upon layer of spinning wheels linked by interlocking cogs, screws and wires. Some of the cogs are so tiny they're barely visible. Size doesn't matter—what's ...

A new study from marine scientists at the University of Georgia reveals two important compounds not previously considered that are released into the ocean's dissolved organic matter pool by phytoplankton ...

Fertilizers are known to promote the growth of toxic cyanobacterial blooms in freshwater and oceans worldwide, but a new multi-institution study shows the aquatic microbes themselves can drive nitrogen and ...

Researchers have created a model that considers how different stages of a plant's life cycle interact with each other. Whereas previous studies have examined the seed, vegetative, and reproductive phases ...

An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plants and microorganisms that would unsettle one of the largest carbon reservoirs on the planet—soil.

A new study is helping to answer a longstanding question that has recently moved to the forefront of earth science: Did our planet make its own water through geologic processes, or did water come to us via ...
